Some people, maybe valuing the art-world’s judgement from knowledge and experience, feel it is worth that. Some people also like Seurat :) . Turbo appreciates Monet. From heated previous threads Zoobyshoe and Cyrus are among others who like Pollock. Some may prefer to see a real bowl of flowers sitting on their kitchen table.
I imagine those who work in astronomy may have a special appreciation of the awe inspired by astronomical images. Turbo mentioned being particularly drawn to Monet’s work, and reasoned that it could be to do with his eye-sight, which gives Turbo a particular appreciation for Monet’s sight. From memory, I think Cyrus had studied the Modernism. Often some sort of understanding, be it an understanding for Monet’s sight, or for astronomy, or be it some other means of attaining a familiarity with whatever image, helps us find in images things we can enjoy or find interestingly challenging.
It can be possible to enjoy different things on different levels. The Guardian critic, not unlike Ivan, has said of Serrano’s work (op) generally that it is superficial. I find it interesting on a couple of levels, but I find many other things much more challenging/interesting, so don’t completely disagree with Ivan and think it’s good to discuss and learn from different views.
